FDA Recommends Against Prolonged Use of Magnesium Sulfate to Stop Pre-Term Labor

FDA is advising health care professionals against using magnesium sulfate injection for more than 5-7 days to stop pre-term labor in pregnant women. Administration longer than 5-7 days may lead to low calcium levels and bone problems in the developing fetus. 

The Pregnancy Category for the drug is changing to D from A. Pregnancy Category D means that there is positive evidence of human fetal risk, but the potential benefits from using the drug in pregnant women may be acceptable in certain situations despite its risks.
